    <p>I would like to validate every field in my form when each field lose the focus, when this happens i would like these actions happen:</p> <p>1) in the right side of the field appears an image, a .gif (to represent that the system is checking the user input)</p> <p>2) when finished appears another .gif (which depends of the input, 'sucess.gif' or 'error.gif', for example) and a message on the right side.</p> <p>I don't want to use popup or something like, the user is gonna lose usability and i don't want this.</p> <p>I'm trying to do something like this, this is what i have done so far:</p> <pre><code>&lt;h:form id="form"&gt; &lt;h:panelGrid columns="3" &gt; &lt;h:outputLabel for="first_name" value="First Name:" /&gt; &lt;h:inputText id="first_name" value="#{register.bean.firstName}" &gt; &lt;f:ajax event="blur" render="m_first_name" /&gt; &lt;/h:inputText&gt; &lt;a4j:status name="ajaxStatus"&gt; &lt;f:facet name="start"&gt; &lt;h:graphicImage name="loader.gif" library="images" /&gt; &lt;h:outputText value="Processing ..." /&gt; &lt;/f:facet&gt; &lt;/a4j:status&gt; &lt;a4j:commandButton value="Register !" action="#{register.validateName}" status="ajaxStatus" /&gt; &lt;/h:panelGrid&gt; &lt;/h:form&gt; </code></pre> <p>I was searching for some solution on Google and I think </p> <pre><code>&lt;a:a4j ... &gt; </code></pre> <p>is my best option, because of the <code>onbegin</code> and <code>oncomplete</code> attributes. There's some attribute as these in some native tag in JSF 2 ?</p> <p><strong>UPDATE</strong>: @BalusC approach:</p> <pre><code>&lt;!DOCTYPE html&gt; &lt;html lang="pt-br" xmlns="http://www.w3.org/1999/xhtml" xmlns:f="http://java.sun.com/jsf/core" xmlns:h="http://java.sun.com/jsf/html" xmlns:ui="http://java.sun.com/jsf/facelets"&gt; &lt;h:head&gt; &lt;title&gt;Insert title here&lt;/title&gt; &lt;script type="text/javascript"&gt; function showProgress(data) { var inputElement = data.source; // The HTML DOM input element. var ajaxStatus = data.status; // Can be "begin", "success" and "complete" var messageForInputElement = document.getElementById(inputElement.id + "_message"); switch (ajaxStatus) { case "begin": // This is called right before ajax request is been sent. messageForInputElement.innerHTML = "validating..."; break; case "complete": // This is called right after ajax response is received. messageForInputElement.innerHTML = ""; break; case "success": // This is called when ajax response is successfully processed. if (messageForInputElement.innerHTML.length == 0) { // So, no message has been set. messageForInputElement.innerHTML = "valid!"; } break; } } &lt;/script&gt; &lt;/h:head&gt; &lt;h:body&gt; &lt;h:form id="form"&gt; &lt;h:panelGrid columns="3"&gt; &lt;h:outputLabel for="first_name" value="First Name" /&gt; &lt;h:inputText id="first_name" value="#{bean.firstName}" required="true"&gt; &lt;f:ajax event="blur" render="first_name_message" onevent="showProgress" /&gt; &lt;/h:inputText&gt; &lt;h:message id="first_name_message" for="first_name" /&gt; &lt;h:panelGroup /&gt; &lt;h:commandButton value="Submit" action="#{register.doSomething}"&gt; &lt;f:ajax execute="@form" render="@form" /&gt; &lt;/h:commandButton&gt; &lt;h:messages globalOnly="true" layout="table" /&gt; &lt;/h:panelGrid&gt; &lt;/h:form&gt; &lt;/h:body&gt; &lt;/html&gt; </code></pre> <p>And this is my bean:</p> <pre><code>@ManageBean @ViewScope .. public void doSomething(){ try { Thread.sleep(2000); } catch (InterruptedException e) { e.printStackTrace(); } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
